Problems solved by technology

[0004] However, cow dung is the excrement excreted by cows, which contains a large number of harmful bacteria and indigestible components, which will not only pollute the environment when it is directly put into the breeding pond for fish farming, but also It will cause the fish to face the risk of infection of bacteria, resulting in large economic losses in the fish farming industry

Embodiment 1

[0028] A kind of fish feed, its raw material composition by weight is 35kg of fermented cow dung, 40kg of corn, 10kg of bran, 1kg of salt, 0.9kg of mineral additives, 0.4kg of sodium bicarbonate; % fermented grass.

[0029] The preparation method of the fermented cow dung is based on mass percentage, after mixing 70% of fresh cow dung, 15% of corn flour, 10% of rice bran and 5% of wheat bran into the starting material, and then according to the weight of the starting material Add 0.0015 times of feed starter, and after stirring evenly, add water to adjust the moisture content to 60%, seal it in a fermentation tank, control the temperature at 20°C for 3 days of fermentation treatment, and you are done. Described fermented grass, its preparation method comprises the following steps:

[0030] (1) Preparation of fermentation bacteria liquid: take 1kg of water, boil it, add 1kg of brown sugar, after the brown sugar melts, get brown sugar water, and cool the brown sugar water to 30...

Embodiment 2

[0037] A kind of fish feed, its raw material composition by weight is 45kg of fermented cow dung, 50kg of corn, 13kg of bran, 2kg of salt, 1.1kg of mineral additives, 0.6kg of sodium bicarbonate; % fermented grass.

[0038] The preparation method of the fermented cow dung is based on mass percentage, after mixing 70% of fresh cow dung, 15% of corn flour, 10% of rice bran and 5% of wheat bran into the starting material, and then according to the weight of the starting material Add 0.0025 times of feed starter, and after stirring evenly, add water to adjust the moisture content to 70%, seal it in a fermentation tank, control the temperature at 45°C for 3 days of fermentation treatment, and you are done. In the above-mentioned fermented cow dung preparation process, a traditional Chinese medicine sterilant accounting for 20% of the weight of fresh cow dung is also added thereto, wherein the traditional Chinese medicine sterilant consists of 1 kg of rice straw powder, 0.1 kg of be...

Embodiment 3

[0047] A kind of fish feed, its raw material composition by weight is 40kg of fermented cow dung, 45kg of corn, 12kg of bran, 1.5kg of salt, 1kg of mineral additives, 0.5kg of sodium bicarbonate; % fermented grass.

[0048] The preparation method of the fermented cow dung is based on mass percentage, after mixing 70% of fresh cow dung, 15% of corn flour, 10% of rice bran and 5% of wheat bran into the starting material, and then according to the weight of the starting material Add feed starter 0.002 times, and after stirring evenly, add water to adjust the moisture content to 65%, seal it in a fermentation tank, control the temperature at 35°C for 3 days of fermentation treatment, and you are done. In the above-mentioned fermented cow dung preparation process, a traditional Chinese medicine sterilant accounting for 30% of the weight of fresh cow dung is also added thereto, wherein the composition of the traditional Chinese medicine sterilant is 3 kg of rice straw powder, 0.3 kg...

Abstract

The invention relates to the technical field of fish feed preparation, in particular to fish feed and a preparation method thereof. The proportional design is performed through fermented cow mature, corn, wheat bran, common salt, mineral supplements, sodium bicarbonate and fermented pasture, so that the mixture ratio of all raw materials is reasonable; the nutrition structures can be mutually improved; particularly, the palatability of fermented cow manure can be improved; the eating quantity of the feed fed for feeding the fish is increased; the bringing of harmful pathogenic bacteria is avoided; the culture risk is prevented; the safety coefficient is improved.

Description

technical field [0001] The invention relates to the technical field of fish feed production, in particular to a fish feed and a preparation method thereof. Background technique [0002] As the feed for fish farming, raw bait (fresh or frozen horse mackerel, mackerel, sardine, sand eel, squid, etc.) that is also consumed as bait in nature comes to mind first. Raw bait is the original natural bait of fish, so it is excellent in terms of fish preference and nutritional benefits of fish, but raw bait suffers from many problems such as stable supply and stable product quality because it is derived from natural resources. Wet pellets obtained by blending vitamins, minerals, natural starch, etc. Particulates can cause environmental pollution problems. [0003] In recent years, the rapid development of the aquaculture industry, especially the relatively rapid development of the fish farming industry, has led a large number of researchers to start researching on fish feed, some of ...
